May flag high-risk cardiac surgery patients for closer monitoring; leaves open whether these factors inform preventive strategies in prospective trials.
What are the independent predictors for permanent pacemaker requirement following open heart surgery, and how does it impact resource utilization?
Permanent pacemaker insertion after open heart surgery is independently predicted by aortic valve surgery, absence of preoperative sinus rhythm, postoperative MI, and female gender, and is associated with significantly increased resource utilization.
Rizzo et al. (1996) studied this question.
